OUTPUT SELECT AND ENABLE CONTROL
Register bits MX controls the output selection. The output select block consists of a summing stage
and an input select switch for each input allowing each signal to be output individually or summed
with other signals and output on the analogue output. The default for the output is DAC playback
only. VOUT may be selected to output DAC playback, AUX, analogue bypass or a sum of these
using the output select controls MX[2:0]. For example, to select sum of DAC and AUX, set MX[2:0] to
011.
The output mixer is powered down with DACD.
